ABSTRACT

Introduction: appendiceal adenocarcinoma is a rare neoplasm whose diagnosis is usually incidental after an appendectomy performed for acute appendicitis. Objectives: to report an uncommon case of welldifferentiated appendiceal adenocarcinoma diagnosed incidentally and to highlight the relevance of routine histopathological examination of appendectomy specimens. Case presentation: a patient operated on for acute appendicitis was analyzed. Histopathological findings revealed an adenocarcinoma of the appendix, prompting a right hemicolectomy with ileotransverse anastomosis. Results: histopathological examination of the appendix revealed a well-differentiated adenocarcinoma with deep layer infiltration and involvement of the surgical margin. A radical right hemicolectomy was performed. The approach was complemented with thoracoabdominal computed tomography and circulating tumor DNA detection studies, which were negative and supported adequate oncologic control. Conclusions: routine histopathological evaluation of appendectomy specimens is essential, as the diagnosis of cecal appendiceal adenocarcinoma is often incidental. Emerging tools such as circulating tumor DNA may contribute to proper staging and surveillance.
